Zusammenfassung:	A method for determining a change in a coefficient of friction (335) for a fully released friction clutch (120) in a drive train of a motor vehicle comprises steps for determining (225) a period (425) during which the friction clutch was released, determining (230) a rotational speed (430) of the friction clutch, and determining (235) the change in the coefficient of friction (335) on the basis of the period (425) and the rotational speed (430), the change in the coefficient of friction (335) being determined by means of a characteristic field (315). 种用于确定完全断开的摩擦离合器(120)的摩擦系数变化(335)的方法，所述摩擦离合器用于机动车辆的动力传动系中，该方法包括下述步骤：确定(225)时间段(425)，在所述时间段期间所述摩擦离合器断开；确定(230)所述摩擦离合器的转速(430)；并且根据所述时间段(425)和所述转速(430)确定(235)所述摩擦系数变化(335)，其中借助于特征曲线族(315)确定所述摩擦系数变化(335)。
